[Tectal tumours in paediatrics. A review of eight patients].
INTRODUCTION: Tumours of the tectal region form, within the group of gliomas of the brain stem, a sub group with better prognosis which require a different therapeutic strategy. OBJECTIVES: A retrospective review of tectal tumours in children to find the most suitable therapeutic approach and the prognosis to be expected. PATIENTS AND METHODS: We reviewed 8 paediatric patients who, during the past 11 years, had developed tectal tumours diagnosed by means of neuro imaging techniques. We evaluated their clinical features and especially their clinico radiological progress. RESULTS: The average age at the time of diagnosis was 10 years. All cases presented with the clinical features of raised intracranial pressure secondary to obstruction of the aqueduct of Sylvius. MR was the key to visualization of the tectal lesion in all cases but one, which had already been shown on CT. The initial and only treatment given was a ventricular shunt. The average clinico radiological follow up in our series was 4 years, with good progress in all cases so that no other therapeutic measures were required. MR follow up showed that the tumours were stable in all cases but one, which had increased slightly in size but without parallel clinical signs. CONCLUSION: In most cases tectal tumours in children follow a benign course. A ventricular shunt is usually the only treatment necessary. However, close clinical and radiological follow up should be carried out to rule out growth of the tumour which make other treatment also necessary. MR is the method of choice for initial evaluation and follow up of these tumours.

[Frontal sinus osteoma associated with intracranial porencephalic cavity].
A case of an eighteen-year-old student, complaining of frontal and periorbital headache is presented. Using conventional radiographies and CT Scan a frontal sinus osteoma is diagnosed, finding a hypodense image located in the left frontal cerebral lobe, without perilesional oedema or contrast uptake. During the surgical act, a destruction of the posterior wall of the left frontal sinus is found, penetrating the anterior cerebral fossa and connecting with the cerebral cavity in the left frontal cerebral lobe through a fistula of mucosal tissue that passes through the dura mater. Complete tumoral exeresis was undertaken as well as plastic reconstruction with excellent clinical and cosmetic results. We conclude that the early diagnosis and treatment of these benign lesions should be undertaken in order to avoid the potential complications they can provoke.

[Presbyphonia: a study of acoustic parameters of normalcy].
The voice records of 36 healthy men and women over 65 were studied for the purpose of defining age-related changes in voice. The pattern of changes differed in men and women. Among other changes, compression of vocal range and extension, difficulties in intonation, and F0 changes were found.

[Intracranial hypertension syndrome due to giant frontoethmoidal osteoma].
Osteomas are benign lesions that may cause life-threatening complications. Their radiological diagnosis usually is casual. Once diagnosed, periodic radiological follow-ups should be carried out and if growth occurs, surgical measures should be taken to prevent complications. The case of a 53-years-old white male admitted for injuries produced by a traffic accident is reported. He had a history of frontalization syndrome with episodes of disorientation and behavioral changes. Plain radiography, CAT, MRI and bicarotid angiography revealed a bone mass that occupied almost the entire anterior fossa. Intracranial hypertension syndrome caused by a giant ethmoidal osteoma was diagnosed. Surgery using a frontal approach was undertaken.

[Infantile peripheral facial paralysis].
Peripheral facial paralysis is a common mononeuropathy in adults. It is less frequent in children, but is very upsetting for parents when it occurs. Its causes in children are similar to those found in adults, the most common being idiopathic. However, secondary facial paralysis is the most frequent cause in children. The results of a 4-year follow-up of 29 cases of peripheral facial paralysis in 26 children age 14 and under are reported. The causes, evolution, treatment, recuperation, care, and rate of admission are reviewed. Results are compared to those found in the follow-up of 196 adult cases of peripheral facial paralysis made by the authors.
